{"version":"1.0","type":"rich","title":"Learning","description":"This example demonstrates the VizHub V3 runtime environment’s “Hello World” starter, showing a single line of text whose font size is mutable via Alt-drag on the numeric value in the code editor. The code exports a `main` function that receives a `container` DIV and writes an HTML string with an inline style, enabling continuous hot reloading through interactive widgets. It introduces the simplified entry point without an `index.html` file, relying on the container’s measured dimensions for layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12c9e8929967449883d287abfba9a179?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
